5. Summary of concepts

 

 

Clusters and system administration

1. How can I use clusters?
2. How does the system administrator benefit?
3. What about my applications?
4. How do I set up a cluster?

 

 

First tasks

1. Set up a new cluster
2. Add queue manager to a cluster
3. Add queue manager to a cluster -- using DHCP

 

 

How queue manager clusters work

1. Components of a cluster
2. What makes clustering work?
3. Using aliases and remote-queue definitions with clusters

 

 

Using clusters for workload management

1. More than one instance of a queue
2. Programming considerations
3. MQI and clusters
4. Return codes

 

 

Using WebSphere MQ commands with clusters

1. MQSC command attributes
2. WebSphere MQ commands for work with clusters

 

 

Managing WebSphere MQ clusters

1. Designing clusters
2. Maintaining a queue manager

 

 

Keeping clusters secure

1. Stop unauthorized queue managers from sending messages to a queue manager
2. Stop unauthorized queue managers from putting messages on queues
3. Stop a queue manager from putting messages to remote queues
4. Prevent queue manager from joining a cluster
5. Force unwanted queue managers to leave a cluster
6. Using SSL

 

 

Advanced tasks

1. Add a new queue manager that hosts a queue
2. Remove a cluster queue from a queue manager
3. Remove a queue manager from a cluster
4. Move a full repository to another queue manager
5. Convert an existing network into a cluster
6. Add a new, interconnected cluster
7. Remove a cluster network
8. Add new queue managers that host a shared queue
9. DISPLAY CLUSQMGR shows CLUSQMGR names start SYSTEM.TEMP
10. MQRC_UNKNOWN_OBJECT_NAME opening a queue
11. MQRC_CLUSTER_RESOLUTION_ERROR opening a queue
12. Messages are not appearing on the destination queues
13. QALIAS message's put to the SYSTEM.DEAD.LETTER.QUEUE
14. Queue manager does not up to date information
15. Changes in the cluster not reflected in the local queue manager
16. DISPLAY CLUSQMGR, shows a queue manager twice
17. Queue manager will not rejoin the cluster
18. Resolve Problems

 

 

Cluster workload exit call and data structures

1. Cluster workload exit
2. Cluster workload exit parameter structure
3. Cluster workload destination-record structure
4. Cluster workload queue-record structure
5. Cluster workload cluster-record structure
6. Navigate Cluster workload records

 

 

Constants for the cluster workload exit

1. List of constants
2. Character string and byte fields
3. Binding
4. Channel status
5. Cluster queue type
6. Persistence
7. Inhibit put
8. Queue flags
9. Queue-manager flags
10. Destination-record length
